Abstract
An interleaver circuit architectures, which utilizes the relationship between intra-row elements in a matrix, in order to simplify the MOD computations necessary in an interleaver. The interleaver calculates a subset of results, stores those results, performs operations on the stored results in order to obtain new results, then updates at least some of the old results with the new results for the next column operation. The interleaver address is then calculated row by row. By storing only a subset of the results and replacing old results with new results, the interleaver can calculate the interleaver address 'on the fly' in one clock cycle with very little delay. The interleaver may also require less power and smaller substrate surface area.
